Scored a uni. antenna(new) off e-bay sticks to window with double sided tape,unfortunately it did not come with instructions.It has a braided wire where it connects to window figured it was ground.On the other end it has a small red wire that comes out by the ant jack that plugs into head unit what the heck is this wire?I ground it and no differance,no replys on my e-mail I sent to seller ,what would it do if I plug it to hot wire?
